50A to 300A, Scalable µModule Regulator Needs 60% Less Capacitance to Power Sub-28nm GPUs, FPGAs, ASICs & Processors

Linear Technology, now part of Analog Devices, introduces the LTM4650-1A and LTM4650-1B, dual 25A or single 50A µModule® (power module) regulators scalable to deliver 300A to high power, low voltage sub-28nm GPUs, FPGAs, ASICs and microprocessors. The low core voltage of these digital devices requires very accurate voltage regulation at both steady state (DC) and fast load current transients. The LTM4650-1A guarantees ±0.8% total DC voltage accuracy over reference, line, load and temperature (̶ 40℃ to 125℃), whereas the LTM4650-1B guarantees ±1.5%. Both devices can be optimized for ±3% or better total error band, including load step transients with a minimum number of ceramic capacitors to meet the core voltage window requirement of sub-28nm digital ICs.
